Pneumatic Actuators
The MeridianTM Pneumatic Actuator
DRC Series Features & Benefits:
The MeridianTM Pneumatic Actuator has proven to be the most reliable
actuator by providing a minimum number of dymanic seals, leading to
an extremely long life. Conventional scotch yoke actuators have rod and
piston seals, while the Meridian high performance actuator requires no
rod seals and has a long life LOW FRICTION LIP SEAL on the piston.
Seals: It is recommended that the right material is selected depending
on the application:
NBR - Normal application with temperature limits from -40o C to +80o C.
Seals have good wear and tear properties. The elastomer has a shelf
life of up to 5 years from assembly. Seals show a good resistance to all
lubricating oils and perfom better under continuous lubrication. This is the
standard seal.
EPDM - Applications having air with high moisture content are
recommended with EPDM. It has a better resistance for low temperature
applications. Standard EPDM can stand up to -30o C and H-EPDM
is suitable up to -45o C. It has fair resistance to wear and tear. The
elastomer shelf life is up to 7 years from assembly.
VITON - Viton is suitable for high temperature environments and can
withstand up to +140o C. It is essential that the right grade of lubrication
is used for this application. Please consult Meridian for the correct
lubrication necessary. It has average resistance for wear and tear. The
elastomer shelf life is up to 10 years from assembly.
Standard Paint Finish: Meridian follows a high quality corrosion
protection system on its actuator. The actuator is painted using a twopart epoxy system. The actuator has an epoxy based primer of 10
micron thickness and then epoxy paint is applied to 30 - 40 micron
thickness. Meridian certifies this painting system for 200 hours salt
spray test.
Low Friction Lip Seal
End Stroke 0o & 90o
Output Shaft:
Male Double ‘D’ - This option is designed to take torque as stated with
minimal coupling space. It is the most compact and has self-aligning
properties.
Female ‘F’ - This option is per ISO 5211. These dimensions provide
interchangeability with most high torque actuators.
Special Version: Meridian has the ability of designing special features
as required by the customer. Such options are covered by Meridian
under the option of SU.

Spring Set
Spring set 5, 6, or 7 are Meridian pre-loaded spring cartridges. Customer cannot vary torque. For changing code
from 5, 6, or 7, customer must change the cartridge.
Different torque figures can be achieved by changing Spring design. Consult Meridian for special requirements.
Caution: It is dangerous to dismantle cartridge. It is dangerous to drop the cartridge. Do not apply any external
load.

Rotary Actuator Corrosion Protection Options
Body
Hard Anodized Aluminum: Standard
• Special Aluminum alloy (6351T6) used as a base metal
• Hard anodizing of aluminum results in better corrosion protection,
surface hardness and superior wear resistance
• 50 micron thickness of controlled oxidized surface of the Aluminum alloy
is comprised mainly of Aluminum Trioxide (Al2O3) crystals along with
Magnesium and Tungsten oxides, which makes the surface chemically
inert and extremely hard (in excess of 45Rc)
• Being an oxidized layer of the base metal Aluminum, the treated layer
cannot be peeled off, making this an extremely stable surface treatment
• Surface withstands all enironments including saline, with the
exception of strong acidic and alkaline atmospheres
Electroless Nickel Treatment: ‘EN’
• Nickel is deposited on the aluminum surface (not electrolytically) by
chemical reaction of nickel on the Aluminum body
• The treatment covers the crevices including threads and passage
holes, leaving the surface completely non-porous. Superior corrosion
resistance as compared to hard anodizing makes this treatment a
suitable choice for corrosive environments. Ideal for external wash.
Epoxy Coated Actuators: ‘CL’
• Two part epoxy system deposition on the prepared (hard anodized)
Aluminum body by spray technique. Produces a 30 - 40 micron thick
layer (only external surfaces). Epoxy coating helps in protecting the
actuator from extremely corrosive environments. Choose this option
specifically for acidic or alkaline environments. This option is also
suitable for environments such as Ammonia, and Ammonia Liquor.
Meridian guarantees a 200 hour salt spray test.
Pinion
Electroless Nickel Plated: Standard
• Standard surface treatment given to the steel pinion shaft (EN 8).
Adequate for most applications including corrosive environments.
Stainless Steel: ‘8/8M’
• Optionally available for aggressive environments. Pinion can also be supplied in
SS304/SS316.

3 Position Rotary Actuator
Double / Single Acting
3 Position Mechanical Stopper
Features:
• Actuators suitable for Coarse to Fine adjustment
typically for batching operations or processes
• Repeatability 100%, since stopping is by mechanical

stoppers. Makes it suitable for applications calling
for precise fine to coarse adjustment like in a typical
liquid filling system
Actuator can be switched to one position from any
position very easily with the Solenoid control
3rd position achieved by mechanically stopping the piston movement in the return stroke by
Pneumatic Stopper Pistons
Intermediate position preset at 20% opening. The opening can be adjusted as required by set screw
Actuator as a standard works in reverse action as opposed to conventional configuration. i.e. piston
inward stroke opens the valve and piston outward stroke closes the valve
End stops (+/- 10 degree) are provided on the closing side of the actuator for setting valve closing
precisely
180 Degree Rotary Actuator
Double / Single Acting
Features:
• Suitable typically for 3-way valves requiring ON-OFF
operation
• Available in both Single Acting (Spring Return) or Double
Acting versions
• Single acting 180 degree actuator can provide centre off for

Can be converted to 3-position 0-90-180 degree actuator for
3-way valves using Meridian Limit Switch and NAMUR Valve
type 30138
End-stop adjustment provided for opening direction as a
standard
Actuator mounting is per ISO 5211 and accessories to
NAMUR
For dimensions, weights and air consumption data, refer to
the tables provided
180 degree actuator has 50% of torque value of a 90 degree actuator
